I think it would avoid tip rolling for quite a big group. Of course, audiophiles can't be helped and we will always look (listen) for better!
But there's also a group that finds foam tips simply uncomfortable and/or too sealed off (having the impression of being in a vacuum) and for those customers silicone tips would have avoided even having the question of how to solve their problem. I mean, not every buyer is on a forum like this.
One other thing to note is that I don't think I've seen anyone on this forum trying different foam tips. That's probably partly because they're simply there and that convenience means that a large group will say "okay, those will probably do". I'm not trying to make a point though other than that I think it's a bit cheap. Not very different from the first phone makers that left out a cable, power adapter, whatever. Didn't matter to most, but was very annoying for some. It's like buying a car without wheels because they could have taken the wheels of(f) their old car
